I do not know if there are rules in the forum regarding this, but I believe that once the post is published, it will become the property of the forum and is no longer yours alone.

Such a question was raised about the rights of members and the rights of the forum when a member deleted a post containing good educational content. The objection was: Does he have the right to delete this educational content after he published it on the forum or not? But I think we haven't got a clear answer yet.
